The air conditioner indoor unit provided by this embodiment will be illustrated below with reference to the accompanying drawings.

Fig. 1 is a schematic structural diagram of an air conditioner inner unit provided by an exemplary embodiment of the present invention; Fig. 2 is a structural schematic diagram of an air conditioner inner unit (with the front panel hidden) provided by an exemplary embodiment of the present invention.

Please refer to Fig. 1 and Fig. 2, the air-conditioning indoor unit provided by the present embodiment includes: a casing 1, a water washing device, an anion device 3 and a control unit. Parts of the water washing device and the negative ion device 3 are arranged in the casing 1 . The control unit is communicatively connected with the washing device and the negative ion device 3 .

The case 1 has a frame 11 , an upper case and a lower case. The upper casing is installed on the upper part of the frame 11, and is used to enclose an upper chamber for accommodating equipment such as an indoor heat exchanger. The lower casing is installed on the lower part of the frame 11, and is used to enclose a lower chamber for accommodating equipment such as a water washing device. The front side of the upper casing is provided with an air outlet, and there may be multiple air outlets, so as to improve the cooling or heating effect.

The lower casing of the casing 1 has side panels installed on both sides of the lower part of the frame 11 and a detachable front trim 12 located on the front side of the frame 11. The side panels and the front trim 12 at the installation position together form a lower Chamber, washing device and at least part of negative ion device 3 are located in the lower chamber. Wherein, when the front decorative panel 12 is located at the installation position connected with the frame 11, it blocks the washing device and at least part of the negative ion device 3.

The negative ion device 3 is arranged on the top of the water washing device, and the negative ion device 3 is used to generate negative ions under the effect of high voltage current, and the negative ion can contact with the washing liquid in the water washing device and form water ions.

The water washing device includes: a water tank 2 and a water washing unit. The water tank 2 is used to accommodate washing liquid. The water tank 2 is provided with an air inlet for fresh air to enter, and the air inlet can be arranged on the side wall of the water tank 2. Optionally, the air inlet is arranged at a relatively upper position on the side wall of the water tank 2, so as to prevent the water tank 2 from The washing liquid inside flows out. The air outlet can be arranged on the top cover of the water tank 2 . A water washing unit may be arranged in the water tank 2, and a part of the water washing unit is in contact with the washing liquid in the water tank 2. The lower end of the water tank 2 may be provided with a driving member. The driving member is used to drive the water washing unit to rotate.

Optionally, the water washing unit includes a water throwing part, and the function of the water throwing part is to rotate under the drive of the air-driven motor to absorb water from the lower end of the water throwing part to the upper end, and to throw water from around the water throwing part in the form of a water curtain. Finally, the water thrown out re-flows into the lower end of the water tank 211 under the action of gravity, so as to realize the recycling of water. Specifically, a gap is formed between the lower end of the water rejection part and the bottom surface of the water tank 211. The lower end of the water rejection part is provided with a water inlet, and the side wall of the water rejection part is provided with a plurality of water outlet holes. Driven to rotate to suck water into the water throwing part and make water throw out from the water outlet hole to form a water curtain.

Since there are multiple water outlet holes on the side wall of the water removal part, when the water flow rises to the height of the water outlet hole, it will flow from the water outlet hole. Throw out at a high speed, thereby forming a circle of water curtain in the circumferential direction of the water thrower. After the water-slinging part is thrown out of the water curtain, the air entering from the air inlet of the water tank 2 will contact the water curtain, thereby completing the washing of the air.

Molecules are captured to form negative ions, which can contact the water in the water tank 2 and form water ions.

The negative ion generator can be set correspondingly with the water thrower. Negative ion generator can be positioned at the top of water throwing member. The spraying range of the negative ion generator can correspond to the water curtain formed by the water thrower, so that more negative ions can contact the water curtain to form more water ions.

The particles and solubles in the purified air can also extinguish the active substances such as bacteria in the air to be purified, so that the quality of the air entering the room can be effectively improved. In addition, water ions can also adjust the concentration of positive and negative ions in the air to be purified.

Of course, the negative ions generated by the negative ion unit can also directly contact the washing liquid contained in the water tank 2 to form water ions. At this moment, the water sucked into the water-removing part can have water ions, forming a circle of water curtain containing water ions in the circumferential direction of the water-repelling part. The particles and solubles in the purified air can also extinguish the active substances such as bacteria in the air to be purified, so that the quality of the air entering the room can be effectively improved.
